Good afternoon everyone, I have an Arduino Severino, who has a serial output, with atmel8. I'ma freshman in Arduino and I wonder if the PC to send commands to the arduino I have to use a MAX232 and connect you entries RX and TX arduino or if I can send commands through the serial cable that connects directly to the serial input arduino. If you must use the RX / TX arduino how do I program these inputs to receive data from the PC. Initially I just wanted to make a program to control the turning on and off an LED, and then move to control a motor.
Thanks and await answers.
